They will be applied when calling ``->cloneVar()`` afterwards.

Before dumping it, you can further limit the resulting
:class:`Symfony\\Component\\VarDumper\\Cloner\\Data` object by calling its
:method:`Symfony\\Component\\VarDumper\\Cloner\\Data::getLimitedClone`
method:
- the first `$maxDepth` argument allows limiting dumps in the depth dimension,
- the second `$maxItemsPerDepth` limits the number of items per depth level,
- and the last `$useRefHandles` defaults to `true` but allows removing internal
objects' handles for sparser output,
- but unlike the previous limits on cloners that remove data on purpose, these
limits can be changed back and forth before dumping since they do not affect
the intermediate representation internally.

.. note::
When no limit is applied, a :class:`Symfony\\Component\\VarDumper\\Cloner\\Data`
object is as accurate as the native :phpfunction:`serialize` function and thus
could have a wider purpose than strictly dumping for debugging.
